Congrats to all winners, And I checked out the schedule and there is two more book promotion for the same technology is coming out in the same month.. And I make sure next time, my name is there, as a winner ...

Happy to help! I'll let Ed Burnette take the lead next week, but don't worry, I'll still be here!

To the winners, congratulations! I really rather recommend the subscription. That's all books and all updates for a year, so you will get much more material via the subscription. Right now, you will get access to one published book and two that are in progress. By this time next year, there should be at least five books, all kept up to date with major technology releases (e.g., Android books kept up to date with new SDK releases). But, if you prefer the printed edition, that is perfectly fine!
